An electric device having a first body unit and a second body unit connected through a hinge unit is provided. A Flexible Printed Circuit (FPC) having coil portions wrappable around the shafts of the hinge unit is also provided so that when the second body unit pivots or rotates in relation to the first body unit, the FPC's length is automatically adjusted by way of the coil portions coiling and uncoiling about the shafts.

A forced air heat exhaust type of burn-in test apparatus for packages: A first air supply duct provides air to the burn-in chamber and a second air supply duct provides air to supply tubes that direst air into the test sockets that hold the packages. The test sockets have a structure that allows air ventilation of the conductive balls. Accordingly, the apparatus can control the temperature around the packages as well as the temperature in the burn-in chamber, thus preventing conductive ball-melting.

Disclosed are a memory device and a method for fabricating the same. The memory device includes: a substrate provided with a trench; a bit line contact junction formed beneath the trench; a plurality of storage node contact junctions formed outside the trench; and a plurality of gate structures each being formed on the substrate disposed between the bit line contact junction and one of the storage node contact junctions. Each sidewall of the trench becomes a part of the individual channels and thus, channel lengths of the transistors in the cell region become elongated. Accordingly, the storage node contact junctions have a decreased level of leakage currents, thereby increasing data retention time.

An after-image prevention apparatus and method for a plasma display panel having a plurality of address electrodes and a plurality of scan and sustain electrodes arranged in pairs and in a zigzag pattern. An average signal level until the current frame from currently input picture data and an average signal level of each cell until the previous frame as stored in a memory section is calculated. The average signal level is compared with the picture data. An attenuation coefficient is generated corresponding to the difference between the average signal level and the picture data. The picture data is multiplied by the attenuation coefficient to output correction data, thereby preventing an after-image phenomenon on the plasma display panel.
摘要:
A method and apparatus for driving a plasma display panel that automatically controls power using an average signal level that is compensated based on a difference between power consumption at red (R), green (G), and blue (B) discharge cells. The method includes calculating R, G, and B average signal levels, calculating a compensated average signal level using the R, G, and B average signal levels and R, G, and B weights, and controlling the number of discharges for each frame, which is in inversely proportional to the compensated average signal level. The R, G, and B weights are set at a value that reduces a difference between power consumption at the R, G, and B colored discharge cells when displaying the R, G, and B colors in a case where the R, G, and B average signal levels are equal to each other.
摘要:
The present invention provides a method for fabricating a semiconductor device capable of suppressing stresses concentrated at bottom corners of a gate electrode as simultaneously as preventing an oxidation of a metal included in a gate electrode. The inventive method includes the steps of: forming a gate oxide layer on a substrate; forming a gate electrode including at least one metal layer on the gate oxide layer; forming an oxide layer on the substrate including the gate electrode at a temperature lower than oxidation temperature of the metal layer; and etching selectively the densified oxide layer so as to form an oxide spacer on the lateral sides of the gate electrode.
